About this network

An AS handle naming three countries and an internal ticket number, on 256 addresses.

What it's used for

• One national piece of a global corporate network services operation. 256 addresses in a single IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.

Notable

• The whole inventory is 193.149.192.0/24, netname NL-ATTA-980610.
• The AS handle is ATT-CH-0B AT&T Solutions UK dr6348.
• The registry contacts include a network information centre belonging to a different corporation entirely, alongside the current holder's.
• Three addresses were sampled and none returned a name.

Interesting

• The handle is a small archaeology site. It carries a Swiss country code, a two-character suffix, a company division named for the United Kingdom, and what reads as an internal reference number, all attached to an entity registered in the Netherlands. Every one of those fields meant something to someone at the time, and none of them agree with each other now.
• The other corporation's network information centre is still a listed contact. This business was transferred between two large companies, and the registry kept both sets of contacts rather than replacing one with the other, so the record documents the handover instead of its result.
• A /24 with one neighbour, held by a global operation. Multinationals took an AS per country per business unit in this era, and each one is tiny. What looks like a trivial network in isolation is one cell of something much larger, and nothing in the routing data connects the cells.
• The netname uses the two-digit year form, dating the block to 1998.
